I just picked up my e30 from a reputable shop at closing time. I drove off and right away i notice the engine doesn't nt sound right starting at 1800 rpms with vibration that increases with the rpms.and doesn't go away. A few blocks later i am able to put it neutral and rev it up slowly and it does the same thing while in neutral and no load. The Shop is closed, they are gone and I will return tomorow but I would like to gain some knowledge here from the experts on this forum. The sound and vibration are similar to an engine not firing on all cylinders. the shop has had this car for several months. I like the shop and the people at the shop but somethings not right.
The details
I dropped off my 90 325i with bad rings according to the PO. along with a supposed to be good 88k mile M20b25 motor pulled by a different shop for an m50 upgrade. I wanted the good motor freshened up with new hoses, drive belts, compete gasket replacement, water pump, belts, crankshaft seal, motor mounts, oil level sender, thermostat, ignition wires. it was decided to rebuild the head with HD rockers, 274 cam, new head bolts, rocker shaft plug, camshaft seals and gasket. Additionally they thought I should replace the rod and main bearings so we did.
Any common traits with this since it sounds and feels rough in gear under load and with no load.
